UNITED STATES PATENT @Errea JONATHAN S. TIETS, OF JEFFERSONVILLE, INDIANA.

CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 427,487, dated May 6, 1890;

Application tiled December l2, 1889. Serial No. 383,475. (No model.)

To all whom it may concern:

Be it known that I, JONATHAN S. TIBBETS, a citizen of the United States, residing at Jeffersonville, in the county of Clarke and State of Indiana, have invented new and useful Improvements in Carburetors, of which the following is a specification.

My invention relates to certain improvements in that class of mechanism used for carbureting air to generate a combustible vapor for illumination and other purposes.

It is the purpose of my invention to provide a carburetor having two or more separate vapor-enriching chambers, one of the carbureting-cells being employed for storing or holding the vapor as well as carbureting.

It is my purpose, also, to provide means whereby advantage may be taken of the natural separation of the heavier and lighter gases, or hydrocarbon vapors, to obtain a vapor of any desired richness and adapted to the special purpose in view, whether the same be illumination or heating.

It is my purpose, also, to combine with a carbureting apparatus simple means for gaging the depth to which the cells are iilled with oil and indicating the same to the operator, the cells being so constructed and arranged that the upper one of the series shall be filled before the next cell in order receives any oil, the latter being filled by the former.

The invention consists in the several novel features of constructionV and new combinations of parts, hereinafter fully set forth, and then definitely pointed out in the claims following this specification.

To enable others skilled in the art to practice my said invention, Iwill describe the same in detail, reference being had to the aecompanying drawings, wherein- 4 Figure l is a central vertical section of an apparatus embodying my invention. Fig. 2 is a side elevation, part of the wall of the casing being broken away to show the interior. Fig. 3 is a horizontal section on the line Fig. l, looking downward. Fig. 4. is a similar section on the line y y, Fig. l, looking upward. Fig. 5 is a section on the line .e e, Fig. l, looking upward.

In the said drawings the reference-numeral l denotes a drum or casing of any suitable diameter and depth and preferably of circu- In this chamberV the plates 3, the bend being placed upon the A diametrical line and the ends of the plates terminating before reaching the wall of the drum, forming openings 6. These plates extend from the floor of the drum to the top wall '7 of the cell 2.

rlhe numeral 3 represents a vertical pipe extending from above the top of the ground down through the drum and cell 2,. its open end being adjacent to the licor. This pipe is connected to any suitable form of pump to remove water or refuse oil whenever necessary. Near the same pipe is a separate parallel pipe having its lower end terminating at the top of the cell 2, the end of said pipe merely piercing the top wall '7. This pipe is connected with the pressure-pump and furnishes the circulation of air.

Immediately above the cell 2 and separated from it by the wall 7 is a second cell 9, which communicates with the lower cell by means of an opening lO. This upper cell is the counterpart of the lower in every feature of construction, and is preferably of shallower depth, being terminated by the imperforate wall or diaphragm l2. Instead, however, of occupying the entire varea of the drum, the carbureting or mixing chamber is terminated by an angular or V-shaped wall 13, rising vertically from the diaphragm l2 to a point located in the upper portion of the drum. The wall unites with the wall of the drum and forms a chamber 14, which is closed at its top bya walll, said chamber being in communication with the upper cell 2, the air after` a pipe 17, which rises to the top of the drum IOO and contains a wire 13, extending from a oat 19, lying in the lower cell. The rise of this iloat indicates to the operator when the lower cell is iilled with oil to the necessary depth.

The drum or casing is inclosed at its top by a dome shaped wall 20. Penetrating this cover is a pipe 21, which passes down through the chamber 14 and terminates immediately above a pipe 22, which passes through the wall 13 and enters the reservoir-chamber 23, inclosed by the wall of the drum by the cover and diaphragm 12 and by said wall 13-l ln the pipe 21 is arranged a rod or wire 24, which extends above the ground, and said rod operates a valve 25, by which the pipe 22 is opened and closed, a stuffing-box 26 being provided for the rod to prevent escape of gas. This arrangement admits of the reservoir being filled with gasoline through a filling-pipe 27 without any oil entering the cells. The latter may be supplied at any instant by simply raising the valve 25.

Penetrating the cover or top 20 are three independent pipes, one of which 28 extends to the bottom of the gas-chamber 14. The adjacent pipe 29 has its lower end located about midway of said chamber, while the third pipe 30 terminates just beneath the roof of the gas-chamber. A horizontal section of pipe 31 intersects and communicates with all these pipes, and in each of the latter is arranged a valve-stem 32, carrying a valve 33, by which the lower ends of said pipes, or any one or more of them, may be opened and closed.Y

To sustain the valves when closed, any suitable means may be used, and l have shown for this purpose a latch 34:, pivotally attached to each stem and adapted to rest upon the upper end and support the valve.

The different specific gravity of the vapors of the hydrocarbon group is well known, the richer vapors being considerably the heavier, and all the vapors being heavier than atmospheric air. The arrangement of the pipes 28, 29, and 30 is made to take advantage of this fact and to enable the operator to use a vapor or a mixture of vapors exactly adapted to the necessities of each case. For example, by closing the pipes 29 and 30 the heaviest and richest vapor will be supplied by pipe 28, the service-pipe being connected to the latter or to the intersecting pipe 31. This vapor will burn without complete combustion and requires an air-blast or other means to enable the flame to consume the products of combustion. It', however, the pipe 28 be closed and the pipe 29 opened, a remarkable change will be experienced, this vapor burning with a clear brilliant flame wit-hout smoke and with high illuminating-power. If circumstances require, however, the pipe 30 may be opened and vapor from both the pipes be mingled and burned together. Stuffing-boxes 35 are placed in the upper ends of these three pipes to prevent escape of vapor.

In the air-passages of the cells 2 and 9, between the bathe-plates forming said passages,

I arrange absorbents 36, composed of square pieces of canton-Hannel or other suitable fabric. The squares are of such size that when `fastened by their centers to hooks at the top of 'the cell their corners will touch the bottom of the cell. These absorbents are arranged in alternating position throughout the air-passages, and they take up the gasoline by capillary action,and not only greatly increase the vertical flange or collar and the uppermost cell in direct communication with the vaporstorage chamber, an oil-pipe located in the said vapor-storage chamber connecting the oil-reservoir with the uppermost cell, and having a valve provided with a valve-stem rising through the vapor-storage chamber to the exterior of the casing, a `float located in the' lowermost cell and having a stem extended through the top of the casing, and means,

substantially as described, for conducting the l vapors of differentspecitic gravity from different levels in the vapor-storage chamber.

2. A carbureting apparatus consisting of a casing containing in its base two cells divided by a horizontal diaphragm having an opening from which rises a tubular iiange, a vertical wall joined at its top to the wall of the casing and forming the interior thereof into an oil-reservoir and a vapor-storage chamber, a pipe located in the vapor-storage chamber connecting the oil-reservoir with the uppermost cell, and having a valve provided with a stem extending through the top of the casing to be operated from the exterior, and an air-forcin g pipe connected with the lowermost cell, substantially as described.

3. A carbureting apparatus consisting of a casing containing in its base two cells arranged one above the other, having baffleplates and separated by a diaphragm provided with an opening, from the edge of which rises a tubular flange or collar, a vertical wall arranged in the casing and dividing its nterior into an oil-reservoir and a vapor-storage chamber, a pipe located in the vapor-storage chamber connecting the oil-reservoir with the uppermost cell, and having a valve provided with a stem rising through the top and operated from the exterior of the casing, and means for conducting thevapor of dilerent specic gravity from the one vapor-storage chamber at varying heights or levels therein, substantially as described.

4. The combination, with a casing, an oil- IOO IIO

reservoir, and a series of superimposed cells uppermost cell directly opens, and means, such substantially as described, for conducting the vapor of different specic gravity from the one vapor-storage chamber at different heights or levels therein.

5. The combination, with the vapor-storage chamber of a carburetor, of a series of vertically-suspended pipes having their lower ends terminating at different heights in the said vapor-storage chamber for conducting the vapor of different specific gravity from the chamber at different heights or levels, substantially as described.

6. In a carbureting-machine, the combination, with one or more cells arranged in the bottom of a drum or casing, of a vapor-storage chamber comin unicatin g' therewith and inclosed between a portion of thewall of the d rum andan angular or curved Wall rising from the vtop of the cell7 a gasoline-reservoir inclosed between theu remaining wall of the drum and the Wall of the vapor-storage chamber, a pipe communicating with the reservoir and cell through said chamber, `and a valve opening and closing the pipe and having a stem packed through apipe in the vapor-chamber and extending to the surface, substantially as described.

7. In a carbmeting-machine, the combination, with a drum or casing, of one or more cells aranged in the bottom thereof and separated from each other and from the interior of the drum by diaphragms, a vapor-storage chamber formed by a wall rising from the upper diaphragm and uniting with the Wall of the drum, a gasoline-reservoir inclosed between the said diaphragm, the Wall of the storage-chamber, and the wall of the drum, pipes entering said chamber and dropping therein to different points between the top and the bottom thereof, an intersecting pipe having communication with the service-pipe, independent valves arranged in the pipes taking vapor from the storage-chamber, said valves having stems rising to the surface and provided with,sustaining-latches, a pipe conneet-ing the gasoline-reservoirwith the cell or cells through the storage-chamber, and a valve opening and closing said pipe and having a stem operated from the surface, substantially as described.

In testimonywhereof I have affixed my signature in presence of two Witnesses.
